Step-by-step explanation:
If this were to make a triangle, then 30.1 and 0.8 would be the shorter sides and 31 would be the longest side.
The sum of the lengths of the shorter sides is 30.1+0
8=30.9.
Since this is less than the length of the segment that would be the longest side, by the triangle inequality theorem, these side lengths would not make a triangle.
